- Stores endpoints via atomic.Value and adds setEndpoints/getEndpoints to snapshot safely without locks. - Updates Equals to compare endpoint snapshots without locks, fixing race condition in krt.Equal/DeepEqual. - Switches error handling to hasErrors/snapshotErrors/setErrors. The backend path now returns empty ClusterLoadAssinment when errors exist. - Updates tests to seed errors via setErrors and avoid direct field access. - Keeps DP collection returning Backend IR on empty endpoints and relaxes route pass to allow empty endpoint sets. - Passes errors to DP to ensure cluster management.
